LOOSE-LEAF BINDER.

Application lilod March 15, 1905- Berinl No. 250,254.

This invention relates to loose-leafbinders,

and has for its objects to produce a comparatively simple inexpensive device of this char- T acter in which the leaves will be securely I clamped within the binder. one wherein the latter may be initially adjusted to vary its 1 leaf-holding capacity, and one wherein the clam ing (portions of the binder may be readi y an releasing the leaves.

provided at its longitudinal center with a milled head 8 and having right and left hand threaded portions disposed, respectively, on opposite sides of the head 8. Arranged upon and for relatively reverse movement lon itudinallyof the screw-shaft 7 is a pair of blbcks or sleeves 9, disposed, respectivelv, on op oslte sides of the head 8 and each lOVl ed with a fixed arm or extension 10, aving a series of hpngitudinally-spaced perforations ll. Arranged upon and for adjustment longitudinally of each of the arms 10 is a coupling member or head [2, adapted to be fixed I in place by means of a fastening member 13, entered throu h one of the perforations ll,

positively moved for holding or there being pivoted to each of the coupling :1 mcmbers the inner ends of a pair of oppo- Further objects of the invention are to rovide a device of the type described in w ich the tension members employed for actuating I the binder-clamp will have uniform and sii multaneous movement imparted thereto, thus efiecting a uniform clamping action upon the leaves, one wherein the latter will be maintained in perfect alinemeut, and one in which the o crating member employed for actuating t ictension devices may be locked, thus to preventremoval of the leaves from the binder.

with these and other objects in view the invention comprises the novel features of construction and combination of parts more fully hereinafter described.

In the accompanvinq drawings, Figure I is a front elevation oi a binder embodving the invention. Fig. :2 is an end view of the same,

ally the means for locking the operatingscrew against rotation.

Referring to the drawings, it Will be seen that the binder com rises, essentially, a buck section 1 and side 0 amping members or scctions 2 and 3, there being attached to the back 1, preferably by means of rivets 4, end 1 members or sections 5, equipped with bcarsitel v-extended connecting elements or links 14. in turn pivotally engaged at their outer ends, as at 15. respectively, with the clamping members 2 and 3. It is to be noted in this connection that the arm [0 of each block extends through a guidempening 16 in the other block, as seen clearly in Fig. 5, wherebv the blocks are mutually supporting and the arms present a double guide which insures smooth even movement of the blocks upon the screw. and. further. that through the adjustahility of the cou ling members 13 upon the arms an initial :1 justment of the clamping members 2 and 3 toward and from each other for varying the holding capacity of the binder may be obtained.

Formed in the section I is an opening 17, through which the head 8 is exposed, thus to permit of its being rcadilv engaged for 0 eratiug the screw-shaft 7, while arranged at ongitudinally-spaced intervals in the front portion of the I'lllldt'l is a plurality of leaf-centermg members or posts 18. each consisting of a tubular member 19. carried by one of the sections 2 or 3, and a solid member :20, carried by the other of said sections and designed to telescope with the tubular mcniber 19, there being iixcd upon the outer faces of the sections 2 and 3 rigid perforated cars 21, to which are pivotallv connected, by means of hinges 22. metal plates '23, designed to be secured by rivets :24 with the side boards 25, which, as usual, serve to protect thc'leaves 26, secured within the binder.

Curried at one end of the back section 1 and suitably secured to the adjacent end member 5 is a lock-casing '27, containing any appropriate locking mechanism (not shown) ings 6 for an operating member or screw 7, 5 designed for looking the screw 7 against l q l l l l stood that in attaining these ends minor changes in the details herein set forth Ina-v be resorted to without departing from the spirit of the invention.

llaving thus fully described the invention,

i what is claimed as new is clamping members 2 and 3 toward and, from 5 each other is attained oy adj ustiug the coupling members 1'2 longttndmallv of the arms the desircdcapacity of the binder. The parts 1. in a device of the class described. a binder comprising a pan of clamping mem- I hers. an operating-screw rotativelv sustained 10, as heretofore explained. thus to obtain 1 having been thus properly arranged, lhel leaves are recessed at appropriate points to and operattvely connected with the ciamping fit the centeringposts 1N and are then entered between the clamping members '2 and 3 which are actuated through the medium of the operating-screw and the tensioning devices. comprising the coupler members 12 and links H. for securely clamping the leaves in position. it being apparent that as the screw is rotated the leaves 9 will be acted upon. respectively. by the right and left hand threads. thus to cause them to travel toward and from each other and actuate the tension devices for drawing the clamping members together or forcing them apart. according to the direction of rotation of the screw. the sleeves 9 being guided in their movements by the arms 10, as heretofore explained After the clamping members have been properly adjusted for clamping the leaves the operating member or screw 7 may be fixed against further movement through the medium of the locking mechanism 27 '2 thus to prevent unauthorized removal of the leaves from the binder.

From the foregoing it is apparent that I produce a comparativel simple inexpensive device which in practice will admirably perform its functions to the attainment of the ends in view. one wherein the leaves will be securely clamped in place and one in which the clamping members will be positively operated for releasing the leaves, it being underwithin the binder. blocks or sleeves in threaded engagement with and movable reversal by the screw. arms carried bv the blocks, and coupling members adjustable upon the arms members.

2. in a device of the class described, a binder comprising a pair of clamping members, an opera! big-screw rot ativelv sustained within the binder. movable heads threaded upon and operable bv the screw. arms carried respectively b v the heads and extended in relatively lPVtl'St directions. coupling members adjustable upon the arms for obtaining an initial adjustment of the clamping members. and operative conm-etions between the coupling mel'nbers and clamping members.

3. In a device of the class described, a binder comprising a pair of clamping members. an operating-screw rotativelv sustained within the binder. blocks or sleeves in threaded engagement with and movable reverselv by the screw. said blocks being provided with guide-openings. arms carried by the blocks. the arm on each block being movably ex tended through the guide-opcj-ning in the other block. and operative connections between th arms and clamping members.

In testimony whereof I atlix Ill) signature in presence of two witnesses.
